Hands are hard to do. So are ears. I started studying John Rosengrant's
(of Warriors) work. He uses wire armatures for his hands. I do the
same, and then sculpt the fingers individually, letting them cure fully
before moving on. If the armature is in scale, you should be okay.
Like I say, VP/VLS has a lot of real gems too. The first figure I did
of thiers was a German Infantryman wearing the Zeltbahn with a
Panzerschrek slung on one shoulder, and a Kar98 on the other. It was a
really nice figure and a pleasure to build.
They do have thier casting process perfected, that's for sure.
Sometimes the parts come out warped from being de-molded too soon, but
they are very nearly always bubble free, clean castings. The best in
overall part quality by a long shot.
That former club mate of mine did the gun fighter figures, some of the
American Civil War figures and that one Fallschirmjager figure in full
jump gear with the MP40. They were all great figures. He also did those
old pirate busts.
Say what you want about their figures in general, they definitely put 120mm figure modeling on the map.
